I agree that the prospect of yet more climatic emergencies is frightening. Even with everyone doing their small amount to reduce wastage, drive electric cars, recycling, taking fewer trips by plane, etc, it barely touches on the problem.
It needs actual, drastic and unpopular action from governments instead of 'pledges' and making fine sounding speeches.
But I am pessimistic. As a species, we are too used to eating the out of season foods we like, taking foreign holidays and having multiple cars per household. You only need look at the outrage when foreign travel was banned, to see what would happen if we were told to drastically change our comfortable way of life.
Please don't come back at me with 'but what about....(people who don't have foreign holidays or own multiple cars etc). There will always be people to whom this doesn't apply. I'm talking about the majority of people in richer western countries.
The destruction of the Amazon rain forest needs to stop, far more trees should be planted, and as others have said, fire breaks, strengthening of flood barriers and other land management projects.
I just hope that this report is the catalyst needed for real action to be taken, but as I've said, I'm not optimistic about it and I fear for my grandchildren.
